R61P MELSEC iQ-R Power Supply Unit 5V DC 6.5A AC Input | Mitsubishi

The Original New Mitsubishi R61P is a standard AC input power supply unit for the MELSEC iQ-R series programmable controller platform. It converts a wide-range 100–240 V AC input into a stable 5 V DC output rated at 6.5 A, supplying power to the CPU module and all I/O and intelligent function modules mounted on the same base unit. Designed for backplane/rack mounting, the R61P installs in the leftmost slot of an iQ-R main or extension base unit and is the foundation for reliable, high-availability control system operation. With built-in overcurrent and overvoltage protection, an error contact output for external diagnostics, and a compact 54.6 mm width, the R61P delivers dependable power distribution for medium to large automation systems.

Core Engineering Highlights:
100–240 V AC wide-range input (85–264 V AC) | 5 V DC, 6.5 A rated output | 130 VA maximum input apparent power | 20 A inrush current (8 ms or less) | Overcurrent protection: 7.1 A or higher | Overvoltage protection: 5.5–6.5 V | 76% or higher efficiency | 20 ms allowable momentary power failure time | 2300 V AC dielectric withstand voltage | Backplane/rack mounting | 0.41 kg weight
